Layhadi","doi":"10.1111/all.16443","DOIUrl":"10.1111/all.16443","url":null,"abstract":"&lt;p&gt;Food allergy (FA) is a major public health concern, estimated to affect up to 10% of the global population [&lt;span&gt;1&lt;/span&gt;]. Cow's milk allergy (CMA) is the most common FA in younger children, with around 50% outgrowing the condition by the age of 5 (“natural tolerance”) [&lt;span&gt;2&lt;/span&gt;]. However, those who develop persisting CMA often have multiple allergic comorbidities and present with a more severe phenotype. As a result, in some countries, cow's milk is now the most common cause of fatal anaphylaxis in children and young people [&lt;span&gt;3&lt;/span&gt;]. In these patients, historical management has been the complete elimination of milk and milk-containing products from the diet. More recently, oral immunotherapy (OIT) has been used to induce desensitisation and remission to the sensitising allergen [&lt;span&gt;4&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;OIT involves a gradual introduction of small amounts of the allergenic food (i.e., milk, peanut and egg) into the affected person's diet over time, leading to a state of desensitisation, and ideally longer-term remission (previously named ‘sustained unresponsiveness’) allowing the patient to consume the food &lt;i&gt;ad libitum&lt;/i&gt;. This ultimately results in improved dietary flexibility and health-related quality of life. However, OIT is associated with significant challenges, including high rates of treatment-related adverse events including anaphylaxis, adherence issues as well as psychological and logistical implications and burden from the treatment. OIT for CMA appears to be a particular issue in terms of safety [&lt;span&gt;5&lt;/span&gt;]. In addition, outcomes from OIT vary considerably among individuals, with some achieving significant benefits whereas others showing limited or no improvement [&lt;span&gt;6&lt;/span&gt;]. Understanding the key immunological factors driving the response to OIT and identifying biomarkers that identify responders and non-responders and the induction of remission remains a key unmet need.&lt;/p&gt;&lt;p&gt;The recent article entitled “Allergen-specific B cell responses in oral immunotherapy-induced desensitisation, remission, and natural outgrowth in cow's milk allergy” by Satitsuksanoa et al. [&lt;span&gt;7&lt;/span&gt;] interrogated the trajectory profile of allergen-specific B cells during OIT (those who go on to reach desensitised or remission state) uniquely comparing these findings against the development of natural tolerance to the allergy. The study utilised time-course samples from children with CMA who received OIT, children who naturally outgrew CMA and healthy controls. In this seminal article, the authors revealed that albeit in small proportions, Bos 9-specific B cells are found in all patient groups investigated ruling out the common perception that allergen-specific cells are often confined to allergic individuals. Bos 9-specific B cells from healthy controls differ in that they are proficient in producing sIgG1 and sIgG4 but lack the ability to produce sIgE.&lt;/p&gt;&lt;p&gt;Using a single cell transcriptomic approach to fully elucidate ","PeriodicalId":122,"journal":{"name":"Allergy","volume":"80 1","pages":"12-13"},"PeriodicalIF":12.6,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/all.16443","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this knowledge gap, we conducted global untargeted salivary metabolomics in children with EoE. We analyzed saliva as oral mucosa is the initial interface between the triggering allergens and the host mucosal immune system. Additionally, saliva is rich in metabolites and is uniquely suited for noninvasive sampling, especially in children [&lt;span&gt;2&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;In an institutional review board-approved study (#151341), unstimulated saliva samples were collected from 28 children (6–18 years) with known EoE and symptoms of esophageal dysfunction immediately before their esophagogastroduodenoscopy (EGD). Participants were &lt;i&gt;nil per os&lt;/i&gt; for &gt; 6 h prior to their EGD. Demographic, clinical, endoscopic, and histologic features were also analyzed (Table 1).&lt;/p&gt;&lt;p&gt;Per the current guidelines [&lt;span&gt;3&lt;/span&gt;], 19 (68%) had EoE (active EoE [aEoE] = 9 [47%], and inactive EoE [iEoE] = 10 [53%]), and 9 (32%) were non-EoE controls (controls). Liquid chromatography-high-resolution mass spectrometry was used to analyze saliva samples. Downstream analyses of confidence levels 1, 2, and 3a identified compounds matching searched libraries or databases were performed (see Supporting Information for details) [&lt;span&gt;4&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;In all, an abundance of 434 compounds was significantly different ([&lt;i&gt;p&lt;/i&gt; ≤ 0.05] with &gt; 2-fold change [FC]) between EoE and controls, and PLS-DA identified well-defined clustering of salivary metabolites classifying the two groups. Ten compounds from endogenous origins belonging to nucleosides, nucleotides, organic acid derivatives, and organoheterocyclic compounds robustly differentiated EoE from controls. Specifically, 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanol (FC = 6.85; &lt;i&gt;p&lt;/i&gt; = 0.003), and N-Heptanoylyglycine (FC = 3.62, &lt;i&gt;p&lt;/i&gt; = 0.02), were significantly increased in EoE compared to controls. While deoxyadenosine (FC = −4.0, &lt;i&gt;p&lt;/i&gt; = 0.01), deoxycytidine (FC = −3.42, &lt;i&gt;p&lt;/i&gt; = 0.01), and adenosine (FC = −3.55, &lt;i&gt;p&lt;/i&gt; = 0.02) were significantly lower in EoE than controls (Figure 1). Adenosine is known to have anti-inflammatory effects and is actively converted to inosine due to its long-term instability [&lt;span&gt;5&lt;/span&gt;]. We hypothesize that a decrease in adenosine and a corresponding increase in inosine (inosine-41N5) in EoE (compared to control; FC = 1.24; &lt;i&gt;p&lt;/i&gt; = 0.02) could be related to the underlying allergic inflammation. Next, 57 compounds differed between aEoE and iEoE. Of these, urea was significantly high (&lt;i&gt;p&lt;/i&gt; = 0.03), and serylarginine was significantly low (&lt;i&gt;p&lt;/i&gt; = 0.007) in aEoE compared to iEoE, suggesting that EoE activity can impact salivary metabolites (Figure 2b).&lt;/p&gt;&lt;p&gt;Finally, we found 102 compounds with negative FC and 207 with positive FC differentiated aEoE from controls.

We specifically focus on the results of genome-wide association studies in food allergy, which have identified 16 genetic variants that reach genome-wide significance, many of which overlap with other allergic diseases, including asthma, atopic dermatitis, and allergic rhinitis. Identified genes for food allergy are mainly involved in epithelial barrier function (e.g., <i>FLG</i>, <i>SERPINB7</i>) and immune function (e.g., <i>HLA</i>, <i>IL4</i>). Epigenome-wide significant findings at 32 loci are also summarized as well as 14 additional loci with significance at a false discovery of &lt; 1 × 10<sup>−4</sup>. Integration of epigenetic and genetic data is discussed in the context of disease mechanisms, many of which are shared with other allergic diseases.
